Eachine Wizard 1 ESC doesn't arm

[Kian2552]

Hi guys, I have an eachine wizard and I have replaced the pdb on it and since then one of my esc's makes half of the inital start up tones, and doesn't make the final beep. It also does not spin in betaflight when the rest do, I have tried swapping the esc to a different motor and different motor pins and it does not arm still.

Any help would be appreciated,

Thanks, Kian

If you are getting the initial 3 tones but not the final two, this is an indication that the flight controller is not receiving the ESC signal which means one of two things. Bad ESC or bad soldering/wiring problem. Seeing as the problem follows the change to other motors/pads, I'd guess you have a dud ESC
